数学解题中整体思想的运用,就是以开阔的视野看待所考察的对象,要求立足全局,整体思考,统一处理数学问题,经常接受这种思想方法的训练,可以增强思维的广阔性、敏捷性和深刻性.本文举例介绍整体思想在解决数列问题中的应用,供参考.例1若一个有限项等差数列的前3项的和为34,最后 The use of the whole idea in mathematical solution is to treat the investigated object with an open field of vision. It requires that thinking on the basis of the whole situation, thinking on the whole and dealing with math problems in a unified way, and often receiving the training of such thinking methods, can enhance the broadness and agility of thinking And profoundness.This article gives an example to introduce the application of the whole idea in solving the sequence problem.For example 1 If the sum of the first three terms of a finite difference sequence is 34,
